Question

1) C1=15
C2=20
Aflati: Ipotenuza,Perimetrul,Aria,inaltimea
(Triunghi dreptunghic)

2) C1=10
C2=10√3
Aflati: Ipotenuza,Perimetrul,Aria,inaltimea
(Triunghi dreptunghic)

3) d patra=7√2
Aflati:latura,Perimetrul,Aria

Answer 1

1) I²=c1²+c2² (Pitagora)
I²=400+225=625
I=25
P=15+20+25=60
A=c1xc2/2=15x20/2=150
h=?
Ixh/2=c1xc2/2
25xh=20x15⇒h=12

2) I²=c1²+c2²
I²=100+300=400
I=20
P=20+10+10√3=30+10√3
A=10x10√3/2=50√3
A=20xh/2=150
h=15

3) l²+l²=d²
d²=2l²
d=l√2
7√2=d√2⇒l=7
P=4xl=4x7=28
A=l²=7²=49
